Description
Technical Field

Background
Polarization maintaining fiber is an important basic equipment for constituting coherent optical communication and coherent optical fiber sensing system. By artificially manufacturing double refraction in the optical fiber, the propagation constants of two linear polarization fundamental modes in the polarization-maintaining optical fiber are greatly different, so that the random unstable mode-to-mode coupling in the propagation process is effectively inhibited, and the transmission requirements of the polarization-maintaining performance and high-precision signals are met. Theoretically, the sensitivity of the coherent detection method can be improved by about 20dB compared with the sensitivity of direct amplitude detection, so that the coherent optical fiber sensor mainly using the polarization maintaining optical fiber becomes a hot spot of the current optical fiber sensor research.
The detection and alignment of the polarization axis orientation is a key technology for the application of the polarization-maintaining optical fiber coherence field and the manufacture of related devices. The crosstalk can be effectively controlled to be 30dB by the axis-to-axis error smaller than 2 degrees, and the precision requirement of most application occasions can be met. Aiming at the problems of polarization axis detection and positioning, various methods are provided by many scholars and mechanisms according to the physical characteristics and stress structure characteristics of polarization-maintaining optical fibers, the traditional extinction ratio method detection technology, the central image local monitoring technology provided by the rattan storehouse company, the side axis detection technology and the like can well solve the problems, but the technologies have certain limitations, and mainly have the problems of narrow application range, poor optical fiber identification capability or complex device and the like, and the practical cost is higher.
The current microscopic visual inspection method is only suitable for common polarization-maintaining optical fibers with larger difference between the refractive index of the stress region and the refractive index of the cladding, so that the polarization axis can be observed more easily. For some special devices, such as polarization maintaining couplers, in order to improve the performance of the devices, matching type polarization maintaining fibers with small difference between the refractive index of the stress region and the refractive index of the cladding, and photonic crystal polarization maintaining fibers with side surface light irradiation and difficult imaging are needed. For such polarization-maintaining optical fibers, imaging characteristics are not obvious, polarization axis detection is difficult to perform directly through side-polished imaging observation, and the working efficiency and the application range are limited because matching fluid is sometimes used in the axis aligning process.
